Smoke Continues to Rise from Logging and Burning in the Southern Amazon

Illegal logging and associated burning in the southern Brazilian Amazon rainforest continue to emit smoke and particulate matter. The on-site burning of felled trees releases large amounts of particulate matter, carbon monoxide, and volatile organic compounds. The smoke accumulates in the valleys, causing PM2.5 levels in surrounding villages and towns to exceed safety standards; the ash produced by the burning carries nitrogen and sulfur pollutants that are washed into rivers and lakes by rain, degrading water quality. Air pollution increases the risk of respiratory diseases, and the habitat of native vegetation continues to shrink.
